A unicorn uterus refers to a well-developed accessory mesonephric duct on one side of a woman's uterus, forming a well-developed unicorn uterus accompanied by a normally developed fallopian tube. The development of the contralateral accessory mesonephric duct completely stopped. The function of the unicorn uterus may be normal. If pregnant, the pregnancy and delivery process can be normal, but it may also cause miscarriage or difficult childbirth.

Can a single horn uterus be used as a test tube baby?

The success of a single horn uterus depends on the development of the uterus. Uniangular uterus is a congenital uterine developmental anomaly and also a uterine malformation. The uterine cavity of a unicorn uterus is narrower than that of a normal uterus, so if the unicorn uterus is well developed, it can be used as a test tube baby. But if the uniangular uterus is congenital underdeveloped and the muscle fibers are not in tension, even in IVF, if the uterine morphology is abnormal after pregnancy, it can lead to premature birth. Abnormal fetal position in women after pregnancy may be caused by well-developed uniangular uterus.

However, in vitro fertilization generally recommends patients to transfer a single embryo, as if two embryos are transferred, twin pregnancy can lead to some complications, such as premature birth, miscarriage, etc. So in vitro fertilization (IVF) is usually done using a single horn uterus. If you want to use a single horn uterus as an IVF, you hope to comprehensively evaluate the shape and cavity of the uterus through hysteroscopy before pregnancy, and then perform IVF assisted pregnancy. If the uniangular uterus is underdeveloped and cannot conceive on its own, a third-party assisted pregnancy can be considered.

What are the hazards of a single horn uterus?

Many patients go to the hospital for examination because they cannot conceive.

2. During pregnancy, some complications may occur, such as whether the uterine wall or mediastinum is pregnant, which can affect embryonic development and lead to premature birth, habitual miscarriage, premature birth, etc.

3. Abnormal menstruation. Patients without a uterus usually exhibit primary amenorrhea. Childhood Qi has low menstrual flow. There are double uterus, double horn uterus, and compound uterus, with excessive or prolonged menstruation due to the increase in endometrial area.

4. Dysplasia of the uterus is often accompanied by underdeveloped uterine muscles, which can lead to delayed delivery and spontaneous uterine rupture. After delivery, it is easy to experience placental retention and uterine contractions and bleeding.
